Which MikroTik RouterOS versions are affected by CVE-2026-84411?

All MikroTik RouterOS versions prior to 7.24 are affected by CVE-2026-84411 if the web management service is exposed. The vulnerability is fixed in RouterOS 7.24 and later. Note: Devices not exposing the web management interface are less susceptible, but upgrading is still recommended. Source: MikroTik Downloads.

How can organizations mitigate CVE-2026-84411?

Immediate mitigation requires upgrading affected devices to RouterOS 7.24 or later. If immediate patching is not possible, restrict or disable exposure of the web management interface to the internet, limit access to trusted internal networks, place management interfaces behind a firewall, require VPN for remote administration, and monitor for anomalous HTTP requests. These steps reduce risk until patching is feasible. Note: Mitigation steps are only effective if implemented promptly; unpatched, internet-exposed devices remain at high risk. Source: CISA ICS Advisory.

How can I check if my organization is exposed to CVE-2026-84411?

IONIX offers a free exposure report that maps all assets running MikroTik RouterOS, identifies potentially exposed assets to CVE-2026-84411, and confirms which assets are verifiably exploitable. Request a scan at ionix.io/request-a-scan. Note: The accuracy of exposure mapping depends on the completeness of asset discovery and network visibility.

IONIX Capabilities for Zero-Day and CVE Response

How does IONIX detect and validate exposures to new zero-days like CVE-2026-84411?

IONIX continuously maps the external attack surface using multi-factor discovery methods such as DNS analysis, certificate mapping, and metadata inspection. For new CVEs, IONIX analyzes dozens of threat intelligence feeds with agentic technology to detect proof-of-concept code, exploit kits, and active targeting. AI models proactively evaluate exploitability before public PoCs emerge. IONIX then filters exposures by attacker-centric criteria (reachability, authentication requirements, exploitation in the wild) and transforms PoCs into safe, non-intrusive test payloads for validation. This process ensures rapid, accurate identification of exploitable assets. Note: Validation is limited to externally reachable assets; internal-only exposures require additional controls.

What is Live Exposure Defense and how does it help with zero-day CVEs?

Live Exposure Defense is an IONIX capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation inside the same window. This enables organizations to respond to zero-day threats like CVE-2026-84411 before attackers can act. Note: The 12-hour SLA applies to external, internet-facing assets; internal assets require additional processes. Source: IONIX company context, June 2026 launch announcement.

How does IONIX prioritize and mitigate exposures after validation?

IONIX routes validated findings through integrations with ticketing (JIRA, ServiceNow), SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This workflow shortens mean time to remediation (MTTR) and empowers teams to act with confidence. Note: Prioritization depends on accurate asset inventory and integration setup; incomplete data may affect results. Source: Original webpage, IONIX knowledge base.

CVE-2026-84411 – Unauthenticated Remote Code Execution / DoS – MikroTik RouterOS before 7.24

Be the first to know when new zero-days emerge:

Summary

CVE-2026-84411 is a critical integer underflow vulnerability (CWE-191) in the web management service of MikroTik RouterOS, triggered during HTTP request body handling before authentication takes place. An unauthenticated, remote attacker can send a single crafted HTTP request to the exposed web management interface to achieve arbitrary code execution as root or cause a denial of service. The vulnerability affects all RouterOS versions prior to 7.24 and carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: An integer underflow occurs while RouterOS parses the body of an HTTP request submitted to the device’s web management service.
  • Trigger conditions: The flawed parsing logic is reached before any authentication check, so no valid credentials or session are required to reach the vulnerable code path.
  • Attack vector: Network-based (AV:N); exploitation requires only a single crafted HTTP request sent to the exposed web management interface, with no user interaction.
  • Impact: Successful exploitation can grant the attacker arbitrary code execution with root privileges on the device, or crash the web management service, resulting in denial of service. Confidentiality, integrity, and availability impacts are all rated High.

Affected software

  • MikroTik RouterOS versions prior to 7.24 (all devices exposing the web management service)
  • Fixed in RouterOS 7.24 and later

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade affected devices to RouterOS 7.24 or later, available from MikroTik’s official download page (mikrotik.com/download).
  • If immediate patching is not possible:
    • Restrict or disable exposure of the web management interface to the internet; limit access to trusted internal networks only.
    • Place management interfaces behind a firewall and isolate them from business/production networks.
    • Require remote administrators to connect via VPN rather than exposing the web management service directly.
    • Monitor for anomalous or malformed HTTP requests to the management interface as part of a defense-in-depth strategy.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
